Subject: [PATCH V4 0/8] Add EMC scaling support for Tegra210
Date: Wed, 29 May 2019 16:21:31 +0800	[thread overview]
Message-ID: <20190529082139.5581-1-josephl@nvidia.com> (raw)

This series introduces the EMC clock scaling support for Tegra210. The
new version has a significant change, which drops the EMC table bindings
and replaces by memory region node of EMC table.

And most of the comments in V1 have been addressed.
Thanks.

v4:
* make sure the behavior is compatible with the case if the kernel uses
  the older DTB which doesn't have EMC node.
* remove the EMC clock statistic data in EMC debug fs.
